I have a couple of questions. The first should be easy: can someone give me a definition of a long cross? From what I can understand it is just multiples of a single cross. That is to say, rather than just crossing A X B once, it is done multiple times to yield a lot of seeds.

The second question is more detailed. I was wondering if anyone had tried dip - tet conversions on seeds? I have read what I can find on the internet and was just curious if anyone here had experience they would be willing to share?

I believe Fred (Spunky1) has someone who does his conversions for him. Jamie Gossard (Heavenly Gardens) has something on conversions on his website, and there's another one I'll try and look up quickly and get back.

This is a really interesting blog with all sorts of information, so you might want to peruse more of it and I'm sure he'll have other information about conversions in it. That yellow tet conversion of SUNGLASSES NEEDED in his May 23 blog is fantastic!

Thanks Betty! I had seen some of that info. I was wondering more specifically about the method of actual converting seeds at the time of germination. I was going to try using oryzalin (sulfran) in the spring. I can get my hands on molecular biology grade colchicine but frankly, it doesn't seem worth the trouble from what I have been reading.
